. MANUFACTURE OF COLLAR-BUTTONS.

SPECIFICATION forming part of Letters Patent No. 453,253, dated June 2,1891.

Application filed May 29, 1890.

T0 ctZZ whom it may concern.-

Be it known that I, WILLIAM BOURKE, of Brooklyn, county of Kings, andState of New York, have invented certain new and useful Improvements inAdjustable Buttons, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, and tothe letters of reference marked thereon.

My invention relates to buttons for collars, ends, 850., andparticularly to that variety of such buttons now known as adjustablebuttons, wherein one part is made movable or adjustable upon the shankto facilitate insertion through the button hole or holes and removaltherefrom.

The object of my invention is to provide a simple, cheap, and effectivemethod of locating and securing the shank in or on one part, and at thesame time covering the shank, so that the part to which it is immovablyfixed Will be smooth and may be made of like material as the exposedfaces or caps of To accomplish all of this and to secure other andfurther advantages in the matters of construction and use and in respectto economy of production, my improve mentsinvolveacertainnewandusefulmethod, as will be herein first fullydescribed, and then pointed out in the claim.

In the accompanying drawings, forming part of this specification, Figure1 is a vertical view, partly in section and partly in elevation, showinga button constructed after the manner of my invention and involving myimprovements, this view showing the flat or broadest side of the shankand the shoe or movable part turned up, the stationary part having beenfirst completed and the shank afterward inserted and secured. Fig. 2 isa cross-section of the shank and its covershown in Fig. 1, and Fig. 3 anelevation and partial section of the button on a plane at right anglesto that of Fig. 1. Fig. at is a vertical view, partly in section andpartly in elevation, showing thecap detached and ready for applicationafter the other parts are located and secured; and Fig. 5 across-section of the shank and its cover united after the mannerintended to be represented by Fig. 4.. Fig. 6 is a view like Fig. 1, butshowing the shank Serial No. 353,525. (No model.)

fiat or solid instead of being composed of two branches, as in thatfigure.

In all the figures like letters of reference, wherever they occur,indicate corresponding parts.

A is the cap or cover of the main or stationary part of the button.

B is the shoe or movable part, which is hinged upon or movably connectedwith the shank.

C isthe shank, which in the illustrations, Figs. 1, 3, and at, iscomposed of two branches, but which may be otherwise formed, and D isthe cover for the shank, constituting also a cover for the interior ofthe cap A.

Heretofore the cap or outermost portions of the main part of the buttonand of the shoe have most generally been made of rolled gold or metalplated. on one side. The shank has been made of a cheaper metal, ormetal omitting the gold, because it has to be stamped up and fitted andotherwise Worked to such extent as to preclude the use of any plated orcovered metal, because by such working, the, the plating or coveringwould be destroyed. The shank thus left bare not only becomes corrodedand discolors the goods in which it may be worm, but is rough and cutsand abrades the goods. Moreover, the main portion or head of the buttonbeing usually quite thin, as compared with its diameter, does not affordspace to make a union with the shank of such form and character that itwill be as solid and firm as is desirable, rendering soldering orbrazing necessary, and thusdestroying the finish of the button. Toobviate all these disadvantages I draw or otherwise form the cover D ofrolled or plated metal, with a tubular or hollow part projecting fromits center and of length equal to the required length of shank,substantially as shown. This tubular part receives the shank, ofWhatever shape or construction that may be. The cover D and cap-plate Amay be first united, as shown in Fig. 1, thus completing this part ofthe button. The shoe B having been hinged upon the shank O the lattermust then be secured in place within the tubular part of the cover D. Ithas only to be inserted, as shown in Fig. 1, and then the tubular partof the cover pinched or pressed down, as indicated in Fig. 2, so as tofirmly grasp the shank. All this is done quickly and cheaply by use ofsuitable tools and without damage to any of the parts. The resultingbutton has a smoothlycovered shank and an unyielding union between saidshank and the head with all the advantages and none of the disadvantagesabove alluded to.

Instead of securing the shank in the manner above pointed out, it may belocked in place in the tubular part of the cover D before the cap A isaflixed, as indicated in Fig. 4. The union between the cover and shankmay be made secure by simply punching or upsetting the lower end of theshank, as shown in Fig. 4. After this the compressing of the tubularpart may be omitted, as indicated in Fig. 5. IVith a solid shank, as inFig. 6, the locking of it in place may be accomplished after either ofthe above-described plans. hen it is to be located after the cover-pieceand its cap are secured together, it may be slightly indented or bent atone or more points, as a, Fig. 6, and the material of the cover-piececompressed upon it, after a manner which will be readily understood. Themanner of hinging the shoe or the construction of the hinge is notmaterial and may be varied in any desired way.

The invention thus described is found to admirably answer the purposesor objects of the invention above referred to.

Having now fully described my invention, what I claim as new herein, anddesire to secure by Letters Patent, is-

In the manufacture of adjustable buttons, the herein-described method ofsecuring the shank to the stationary part and covering the shank, thesame consisting in drawing or forming a cover-piece for the interior ofthe cap-plate of the stationary part, with a tubular portion adapted toreceive the shank, and then locking together the three parts named,substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand inthe presence of two witnesses.

VM. BOURKE.
